KUALA LUMPUR, Malaysia - The search for a missing jetliner has been expanded well west of its last reported position, toward India, six days after it vanished an hour after taking off for Beijing.

White House press secretary Jay Carney said Thursday that some searchers were being shifted hundreds of miles west of Malaysia, far off course from the intended flight path of the jet.

"It is my understanding the one possible piece of information, or pieces of information, has led to the possibility that a new search area may be opened up over the Indian Ocean," said Carney, who added that the U.S. government "may be allocating" resources to that area to take part in the search.

CBS News and ABC News, citing unidentified U.S. officials, said American investigators believe that two communications systems were shut down separately on the flight deck of the Malaysian Airlines Flight 370, suggesting the aircraft did not suffer catastrophic failure.

The data reporting system, the network reported, was shut down at 1:07 a.m. The transponder -- which transmits location and altitude -- shut down at 1:21 a.m.

Marine Lt. Col. Jeff Pool, a Pentagon spokesman, said Thursday that the USS Kidd is moving to the Straits of Malacca and will arrive in the search area in a day or two.

Meanwhile, Malaysia's acting Transport Minister Hishammuddin Hussein dismissed as "inaccurate" Thursday a report that claimed, based on engine data, that missing Malaysia Airlines Flight 370 may have flown for four hours following its last communication with air-traffic control.

Hishammuddin acknowledged that it is possible that the plane continued flying for a period of time but said a report in The Wall Street Journal stating that engine data from the jetliner continued to transmit information even after the plane lost contact with airport authorities was not correct.

The Journal issued a correction to its report, stating that it was based not on engine data but on unnamed U.S. investigators who analyzed signals sent through the plane's satellite-communication link, which transmits the status of some onboard systems.

The last data transmitted from the engines was received at 1:07 a.m. Saturday on the day the plane with 239 people on board vanished and indicated that "everything is operating normally," said Malaysia Airlines CEO Ahmad Jauhari Yahya.

In another twist in the search-and-rescue efforts now into their sixth day, Hishammuddin said that satellite images released Wednesday by China are not debris from the plane.

The murky images showed what might have been three pieces of debris of significant size, leading to a fruitless search Thursday by Malaysian aircraft in the area indicated, which matched the expected flight path.

Chinese authorities later explained the image release was an accident and did not show Flight 370 plane debris, said Hishammuddin. The publication on an official Chinese government agency website was a result of "personal behavior which is now under investigation," and was not authorized nor endorsed by the Chinese government, he said, reading from a statement from the Chinese Embassy to Malaysia.

The statement echoed remarks earlier from Li Jiaxing, China's civil aviation chief, that China could not confirm the debris pictured was from the missing plane.

Hishammuddin again defended the Malaysian authorities' response to what he called an "unprecedented" and "crisis" situation.

"We have not done anything that would jeopardize this search effort. â?¦ Malaysia has nothing to hide. We have spared no expense and no effort" in a search that he said has expanded to include 43 ships and 40 aircraft, operating on both sides of the Malaysian peninsula.

The original flight plan ran up the east side of the peninsula, over the South China Sea, but the search was extended in recent days to the west side - the Straits of Malacca - after military radar indicated the possibility of a plane making a turn back and flying into that area.

The U.S. Federal Aviation Administration and the U.S. National Transportation Safety Board reviewed the data and agreed with Malaysian authorities that there were "reasonable grounds" to search on the western side of peninsular Malaysia, he said.

Malaysia would not ordinarily release raw data from its military radars, but "in this case we have put the search effort above our national security," and shared data with the USA, China and others, said Hishammuddin.

Like conversations around the world, the plane's fate and mysterious disappearance is dominating discussions in Malaysia. "Maybe it was black magic," said Hairul Nizam, 37, a taxi driver at Kuala Lumpur International Airport. "Why was there no electrical signal from the plane? All our phones give off signals. The U.S. has such good technology, but they cannot find it," he said.

"Maybe there is some news hidden from the people," suggested his friend Zuherrdy Nasution, a sailor from Indonesia who lives in Kuala Lumpur. The most common explanations he had heard involved hijacking or sabotage. Both defended the national carrier, Malaysia Airlines, that Nasution was set to fly on Thursday afternoon.

"It is still a good airline, and the Malaysian government is trying its best," said Nizam.

At the airport's main viewing area, visitors have written hundreds of hopes and prayers on specially prepared sheets and white boards. "Sometimes miracle takes time â?¦ surely you will all come home safe - don't lose hope," read one.

Nearby, KFC employee Hakimi Yusoff took his lunch break Thursday and said Islam would help Malay families deal with their loss. "It was fate, from God, and we must accept the fate of God," said Hakimi Yusoff, 18.
